test/depot_query: add test for zero-sized archives

Browse Source 
This test covers the situation where depot_query evaluates depot content
that is incompletely extracted. In particular, if the 'archives' file
already exists but has a size of zero, depot_query would produce a
page fault. This situation can be manually provoked by deliberately
creating a zero-sized archives file for any otherwise correct pkg.

This patch also fixes the success indicator of the test. It wrongly
matched an early line of the log output.
